Description

Humidifying device with air cleaning function}

The present invention relates to an air purifying humidifying device, and more specifically, to an air purifying humidifying device that can control the humidity of surrounding air by evaporating water.

In general, a humidifier is a device that spews moisture into the air to control indoor humidity. Recently, it is a household appliance that has been widely used for health management purposes such as colds and dry skin by maintaining indoor humidity throughout the four seasons.

There are various types of humidifiers depending on the method of evaporating water, such as ultrasonic type, heating type, natural evaporation type, and complex type. Recently, humidifying devices include a fan that blows moisture-containing air to spread moisture into a wider space. The use of is increasing.

Additionally, as the humidifier uses time, mold and bacteria grow and become contaminated. Contaminated humidifiers must be cleaned periodically as they can cause indoor air pollution.

To this end, Republic of Korea Patent No. 10-1677677 discloses a detachable sterilizing humidifier that has a detachable water tank so that it can be easily attached and detached from the main body, allowing for free installation and movement as well as convenient cleaning and water supply.

The connection portion 162 is installed so that one side is connected to the PCB panel 130. The connection portion 162 is installed to be exposed on the lower surface of the leg 38.

As shown in FIG. 8, when the blowing unit 5 is combined with the water tank 10, the PCB panel 130 is electrically connected to the water level measuring unit 161 through the connection portion 162. It is connected and the water level signal detected by the water level measuring unit 161 is transmitted to the operating unit 140 through the PCB panel 130. The user can easily determine when to resupply water in the water tank 10 through the water level displayed on the display panel of the control unit 140.

In the air purifying humidifying device 1 according to an embodiment of the present invention, when the user operates the control unit 140 and the fan 80 is operated, external air flows into the inlet through the inlet hole 24. As the air flowing into the inflow passage passes through the evaporation induction unit 20, it contains moisture and is transferred to the discharge passage. Afterwards, as the moisture-containing air passes through the filter, fine dust contained in the air is removed. Afterwards, the air from which the fine dust has been removed is discharged to the outside through the discharge hole and adjusts the humidity around the air purifying humidifier 1 according to an embodiment of the present invention.

At the same time, the sterilization unit 90 irradiates ultraviolet rays toward the filter body 72, thereby sterilizing the surface of the filter body 72, preventing bacteria from riding on the air passing through the filter body 72 and contaminating the surrounding air. phenomenon is prevented.

In addition, the air purifying humidifying device (1) according to an embodiment of the present invention is rotated in the second rotation direction (C) while the cover (50) is coupled to the housing (30) so that the coupling piece (53) is inserted into the insertion portion. It can be separated downward through (37a), and as shown in FIG. 5, the user can easily separate and replace the filter 80 accommodated in the discharge passage 31.

And, as shown in FIG. 6, the user rotates the cap 87 to separate it from the drive shaft 87 and then separates the impeller 83 from the drive shaft 87, thereby removing the inside of the impeller 83 and the main duct 34. Makes cleaning easy.

As described above, the air purifying humidifying device according to an embodiment of the present invention is configured so that the user can easily separate the filter 80 and the impeller 83 from the housing 30, making it easy to replace and clean, and eliminating bacteria or mold. It has the advantage of preventing the emission of polluted air due to the propagation of .
